Best Immune Boosters
Vital Health Booster
Long known for its myriad health benefits, vitamin C is one of the most popular nutrients taken in supplement form — and for good reason. This potent antioxidant has been shown to protect against immune system deficiencies, cardiovascular disease, prenatal health problems, eye disease and even wrinkly skin. While many multivitamins and energy drinks, such as Emergen-C, include "superdosages" of vitamin C, the ubiquitous immune system booster can be found in many of our favorite fruits and vegetables, including red peppers, strawberries, broccoli, dark leafy greens and, of course, oranges.
